“CELESTINE Hydra-Plumping Peptide Serum”
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, hyaluronic acid.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

“TARGET CONCERNS → Dehydrated Skin → Loss of Firmness or Elasticity → Enlarged Pores → Over-Active Sebum Production”
This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - hyaluronic acid - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
